What apps do people use also iOS or Android?
I just use the native iOS app.
But when I was looking at eps of In Our Time, the show's been going since 1998 and a heap of them aren't available through iTunes, so I downloaded them and imported them to the phone as music playlists.
I was struggling to work out how to do it, then wondered "what's this?" and found it had imported all of them. You have to delete them manually of course, where the app does it after you've listened to it.
